Generation of lightning infill fails "Infill failed"

[KayGestalten]

Description of the bug

Slicing of the model fails after some time, with the message "infill failed", when using the lightning infill.

Currently I detected the issue only using this model

Using the current live version (2.5.0), there it works

Project file & How to reproduce

jinx-base.zip
Attached the project 3mf

Slicing using the 2.6.0 alpha5 produces the issue

I'm seeing the same thing with the alpha5 release that I do not see with 2.5.0.

Here is another example with the same issue. For me, slicing works with lightning, but if I add a height-range modifier with grid infill at the bottom, slicing fails. The previous version, 2.6.0 alpha4, seems to work fine. Setup: Windows 11, MK3S. See the attached example.

I have provided a bit more detail with my bug report here: #10115

We tested these issues in PrusaSlicer-2.6.0-alpha5+266 and fix will be part of the PrusaSlicer-2.6.0-alpha6

@Ockenfuss , this is probably another issue, but it is recently also fixed. The model is quite heavy, please check it after release 2.6.0-alpha6 and let us know.

I am closing it. Thanks

Thanks, the new version alpha6 seems to solve the issue! Nevertheless, there is a new bug when applying lightning infill on top of another infill. I opened an issue here: #10222
